Extraction of Li, K, and Rb from zinnwaldite by chlorination roasting with CaCl2
Original language description
The extraction of lithium, potassium, and rubidium from lithium mica zinnwaldite was investigated using high-temperature roasting with solid calcium chloride, followed by water leaching of the resulting sinters. This study examined the impact of roasting temperature, heating rate, roasting time, and the calcium chloride content within the roasting mixture on the extraction efficiency of alkali metals. The crucial factors of the roasting process are the roasting temperature and the calcium chloride content within the roasting mixture. The optimal results were achieved when a mixture containing four times the stoichiometric amount of calcium chloride was roasted at 1000 °C for 20 min with a heating rate of 10 °C/min. Under these conditions, 77 % of lithium, 90 % of potassium, and 90 % of rubidium were successfully extracted.
